| Simpler models may be better for determining some climate risk Posted: 25 Sep 2020 08:36 AM PDT Typically, computer models of climate become more and more complex as researchers strive to capture more details of our Earth's system, but according to a team of researchers, to assess risks, less complex models, with their ability to better sample uncertainties, may be a better choice.      |
| Remnants of an ancient asteroid shed new light on the early solar system Posted: 25 Sep 2020 08:36 AM PDT Researchers have shaken up a once accepted timeline for cataclysmic events in the early solar system. Geological and geochemical records indicate that the Earth-Moon system experienced a period of frequent and cataclysmic impacts from asteroids and other bodies. It was thought that this period had a relatively sudden onset, but the researchers have found evidence that this bombardment period may have started much earlier, and decreased in intensity over time. |
| Astronomers model, determine how disk galaxies evolve so smoothly Posted: 25 Sep 2020 08:34 AM PDT By developing better computer simulations, researchers have determined that the scattering of stars from their orbits by the gravity of massive clumps within galaxies leads to a common look in galaxy disks -- bright centers fading away to dark edges. |
| Pair of massive baby stars swaddled in salty water vapor Posted: 25 Sep 2020 08:34 AM PDT Astronomers spotted a pair of massive baby stars growing in salty cosmic soup. Each star is shrouded by a gaseous disk which includes molecules of sodium chloride, commonly known as table salt, and heated water vapor. Analyzing the radio emissions from the salt and water, the team found that the disks are counter rotating. It is promising that salt is an excellent marker to explore the immediate surroundings of giant baby stars. |
| A multishot lensless camera in development could aid disease diagnosis Posted: 23 Sep 2020 09:45 AM PDT A new type of imaging does not require a lens and uses reconfigurable particle-based masks to take multiple shots of an object. The electric-field directed self-assembling mask technology is expected to have uses in lower-cost and faster disease diagnosis, the enhancement of optical microscopy, and may even lead to thinner cellphone technology. |
| Chromium steel was first made in ancient Persia Posted: 23 Sep 2020 06:04 AM PDT Chromium steel - similar to what we know today as tool steel - was first made in Persia, nearly a millennium earlier than experts previously thought, according to a new study. |
| Controlling ultrastrong light-matter coupling at room temperature Posted: 23 Sep 2020 06:04 AM PDT Physicists have managed to achieve ultrastrong coupling between light and matter at room temperature. The discovery is of importance for fundamental research and might pave the way for advances within, for example, light sources, nanomachinery, and quantum technology. |
| New freshwater database tells water quality story for 12K lakes globally Posted: 22 Sep 2020 05:39 AM PDT Although less than one per cent of all water in the world is freshwater, it is what we drink and use for agriculture. In other words, it's vital to human survival. Researchers have just created a publicly available water quality database for close to 12,000 freshwater lakes globally - almost half of the world's freshwater supply - that will help scientists monitor and manage the health of these lakes. |
